Application filed January 19, 1910. Serial No. 538,897.

To all whom it may concern:

Be it known that I, Jnssn A. EoToN, citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in Hoisting-Machines, of which the following is a specification.

The purpose of my invention is to provide a. hoist for raising ore andother material out of a shaft or other excavation, and re moving anddumping the same without the presence of the operator other than at theplace of loading the material. This I. do by the machine illustrated inthe accompanying drawings in which similar reference numerals indicatelike parts throughout the several figures.

Figure 1, is a vertical elevation of the shifting device with one sideremoved, and showing said device in position to be moved to the dump.Fig. 2, is a vertical elevation of the same ready to descend into theshaft. Fig. 3, is a vertical elevation of the bucket and bail. Fig. 1,is a side view of the same with the bucket dumped. Fig. 5, is a plan ofthe Windlass with the cable removed. Fig.- 6, is a vertical elevation ofone end of the Windlass showing the brake and lever raised. Fig. 7, is avertical elevation of the trip ing device. Fig. 8, is an end view of the]2LWS of the tripping device. Fig. 9, is a plan in detail of one of thegripping levers. Fig. 10, is a vertical elevation,- reducedof my machinein place. Fig. 11, is a vertical elevation of the shifting device intripping position. Fig. 12, is a plan on line X X Fig. 2.

I have found that there are many places where the excavator wishes toload the material, hoist and dump it, and have the bucket return to himfor reloading without his leaving the place of loading. This I have madepossible and practicable by my hoisting machine in which amovablew1ndlass drum 1, is carried by a shaft 2, wh1ch shaft has fittedon one end a friction cap 3, and through which shaft are bored holes 4.Within said holes a bar is inserted to prevent the said shaft fromturning when the windlass is in place. Carried by said shaft 2 andfirmly secured on one end thereof is a brake standard 5. Through theupper portion of said standard is fitted a brake shaft 6, on which shaft6 is carried a lever 7 and a friction brake-shoe 8. On the end of saidbrake-shoe is formed a click or pawl 9, which pawl 9 engages the teethof the ratchet wheel 10, which is also secured to the said Windlassdrum 1. On the other end of the said Windlass drum is rigidly secured abevel pinion 11, the teeth of which mesh with the teeth of a gear 12.Said gear 12 is mounted on a shaft 13, which is secured on the saidshaft 2, and at right angles thereto, by the nut 14. Said shaft 13 hasfitted on the other end a handle 15.

Within one end of the shaft 2 is thread- .ably fitted a jack-screw 16,which is provided with openings therein for turning the same. The end ofsaid jack-screw is also fitted with a friction cap 3. When the windlasshas been placed in a horizontal position in the shaft or excavation, theturning out of the said jack-screw will firmly set the Windlass bybringing the ends of the caps in contact with the walls of the shaft andby placing a bar in one of the holes 4 the rotation of the Windlass drumis prevented when the other end of the bar is in contact with the sideof the shaft or excavation. One end of a cable 17 is secured to saidWindlass drum 1, and said cable is passed over a pulley 18 which issecurely fastened to the upright or frame 19. Said cable is then passedover another pulley 20 secured beyond the point where the bucket is tobe dumped to another upright or part of the frame 21. The cable is thenbrought back practically parallel to its reach from pulley 18 to pulley20, where it is passed over pulley 22 which is mounted between the sides23 of the shifting device. The cable is then passed over the bucketpulley 24, and fastened to the lower end of the trip 25. The bucketpulley 24 is mounted between two casings 26, between which casings isalso secured the bucket link 27 and the trip member 28.

In the upper portion of the shifting device, mounted between the sidesthereof, are the traveling pulleys 29, which are made to travel on thecable 30, which cable is tautly secured between the said frames 19 and21.

Pivoted to the upright 19 is one end of the member 31, through the upperportion of which member is passed the said cable 30. The other end ofsaid member is formed arrow shaped to engage the j aws of the grippinglevers 32 and 33. The pivoting of one end and the suspending of saidmember 31 on the cable 30 will permit it to adjust itself to the sway ofthe said cable 30 whether the cable carries a load or not.

ping lever 32, one end of which is pivoted by pin 34, in the slottedopening 35, which slotted opening allows the said lever a limitedlateral motion. Said lever also has therethrough another slot 36transverse in position to slot 35 and near the medial portion of saidlever. The said lever 33 is pivoted near the medial portion by the pin37, and has also a slotted opening therethrough similar to the slot 36in the other lever 32. Onthe side of lever 33-,- adjacent to the lever32 is provided a fulcrum 55. Within slot 36 and its counterpart in theother lever is made to operate the vertical lever 39, also pivoted nearits medial portion by the pin 38 between the sides 23. Said verticallever 39 has secured thereto or formed integral therewith the trip arm40. And on the lower end of said lever is pivoted the detent 41 theother end of which detent engages in the catch of the said member 28,and the side portions of said detent extend beyond the said sides 23through the slotted openings therein, see 12. Guide blocks 42 and 62 arealso secured between the said sides 23, to guide the said trip member 28and to hold it in engagement with the detent 41.

The bucket 43 is mounted on the rollers 44 and axially in each of saidrollers 44 is the pin 45. Said pins are made to move Vertically in theslotted openings 46 that are cut nea-rthe ends of the bail 47. On thelower side of each of said rollers 44, is secured one end of the ropesor cables 48. The other end of each of said cables 48 is firmly attachedto the saidbail 47. The bucket 43 is suspended by the cables 48 and soadjusted that when the said bucket is loaded it will turn over of itsown accord, as the upper end will then be the heavier. Vhen the bucketis empty the lower end is the heavier and the bucket will right itself,and in so righting itself will wind the said cables one half turn on therollers 44, this winding and the fact that when loaded the: upper end ofthe bucket will be the heavier will dump the bucket unless the catches49 engage in the recesses 50 which are cut in the upper edge of thebucket. The said catches 49 are pivoted on the outer side of the bail bythe pins 51, and when the loaded bucket is in a vertical position asshown in Fig. 3', the said catches will engage in the said recesses andretain'the bucket in a vertical position until the bucket is carried tothe tripper 52. Said tripper is pivotally secured to the frame 21, andhasjaws 53 on its outer end, which jaws are formed to press down on theupper ends of said catches 49. The said pressure will release the saidcatches and allow the bucket to dump.

lVhen dumped it will right itself and its ,weight and the inclination ofcable 30 will return it to a position over the shaft. Mounted betweenthe sides 23 is the grip As it nears that position the members of theshifting device will be in the position as shown in Fig. 2. \Vhen nearenough to engage with the arrow pointed end at the member 31 the saidarrow end of said member will slide between the pointed ends of thelevers 32 and and they will be forced apart as shown in Fig. 1. Whenmore directly over the shaft, the point of the lever 32' will strike theshoulder on said member 31 and stop the lateral motionof the said lever32. The other parts of the shitt ing device will move laterally on thepin 34. Said lateral movement will move the upper end of the lever 39and withdraw the detent 41, from its engagement with the trip member 28as shown in Fig. 11. The withdrawal of detent 41 will allow the saidmember 28 to assume the position as shown in Fig. 2. The weight of thebucket and said member will then be on the cable 17, the end of whichbeing attached to lever arm 40 will throw said lever 39 in the posit-ionshown in Figs. 1 and 2. hen the bucket has been filled again andwindlassed up by the pull on cable 17 till the trip member has enteredbetween the guide block 42 and detent 41, the upper point of said member28 will raise one end of lever and lower the other end, the fulcrum 55will raise the gripping end of lever 32, which movement will free theengagement of the jaws on said lever from the arrow end of said member31, and the continuance of the pull on cable 17 will move the loadedbucket and shifting device to the tripper 52, where the load will bedumped.
